The GRACO 238859 is a polypropylene air-operated double diaphragm pump designed for the safe and efficient transfer of a wide range of fluids within GRACO equipment. Its non-conductive polypropylene construction makes it suitable for handling corrosive or aggressive chemicals, and it is commonly used in industrial, chemical, and maintenance applications.

Key Features:

• Air-operated double diaphragm pump
• Husky Series 515 Twistork™
• Polypropylene
• Maximum siphon flow rate: 12 gpm (45.4 lpm) with 100 cps material; 1.2 gpm (4.54 lpm) with 1000 cps material
• Maximum fluid output pressure: 100 psi (7 bar)
• Designed for use with GRACO Husky Series equipment and compatible with a wide range of fluids, including corrosive chemicals
• No mechanical seals to prevent fluid leaks or failures
• Runs quietly at less than 85 dBa with easy-to-use remote muffler
• Center and end porting options for flexible installation
• Reliable and easy to maintain
• Non-conductive polypropylene construction for safety with corrosive fluids

Applications:
Ideal for transferring chemicals, solvents, and other aggressive fluids in industrial, chemical processing, maintenance, and lubrication applications. Suitable for use in environments where non-conductive and corrosion-resistant equipment is required.

Installation Notes:

• Using genuine GRACO parts ensures optimal performance, reliability, and safety, and maintains equipment warranty.
• Ensure proper grounding as per the pump manual, especially since the polypropylene construction is non-conductive
• Follow manufacturer’s instructions for porting and connection options
• Regularly inspect for wear and maintain according to GRACO guidelines
• Use appropriate fittings and hoses rated for the intended pressure and chemical compatibility
